Trump has vowed to deport or incarcerate as many as three million undocumented immigrants with criminal records after he takes office on January 20.
De Blasio said Trump’s stance “flew in the face of all that was great about New York City, the ultimate city of immigrants.”
“The place that has succeeded because it was open for everyone, the place built of generation after generation of immigrants,” he said.
In the wake of Trump’s November 8 election victory, de Blasio said the city would delete from its data base by year-end the names of hundreds of thousands of undocumented immigrants who have received a city ID card, so they cannot be identified or deported by the incoming administration.
The mayor and Trump are known to have strained relations. De Blasio said he stressed to Trump “that I would be open-minded as we continue substantive discussions but also vigilant.”
Like de Blasio, the mayors of other major US cities with high numbers of immigrants have vowed to protect them from deportation, including Los Angeles, San Francisco, Chicago, Boston, Philadelphia and the US capital Washington.
